Switchable LED light source
Switchable LED Light Source contains 10 high power LEDs placed on a revolving disc. The user switches between a selection of monochromatic LED sources and white LED using an application software. It enables controlling also light intensity, duration and a couple of the other parameters. A manually adjustable lens is used to focus light on a sample installed in a photo-electrochemical cell (cell is not included in the setup). The selected by user LEDs are installed on a disk by us prior to the delivery of equipment. However, the LED disc is exchangeable, which means that the user can order a disc with custom LEDs, separately.

Compared to conventional light sources such as halogen and gas discharge lamps, this Switchable LED Light Source offers many advantages such as:
- higher signal-to-noise ratios (due to narrow bandwidth emission),
- better stability,
- longer life (LEDs are operated below their maximum power level),
- lower replacement costs,
- no active cooling requirements,
- no thermal filters in the optical path,
- smaller dimensions, etc.
Switchable LED Light Source is a universal light source for general lab use and OEM applications. It can be used wherever a strong monochromatic LED light is needed. In photo-electrochemistry it is often used as an economy light source for fast screening of photo-catalytic thin films, as well as the broad range of standard photoelectrochemical experiments. It is a versatile light source with LED switching and accurate intensity modulation of each individual LED. The device is compatible with the cages from Thorlabs and TECHSPEC from Edmund Optics.
